Specifically designed to mate with FISO’s optical Easythrough, the 304 stainless
steel Easyplate is mounted on the transformer tank wall by bolting or welding
it on. A 3/8" NPT Easythrough is then screwed on each hole allowing the optical
signal to pass through the tank wall.

One Easyplate can fit as many as 12 Easythroughs. Each NPT hole is numbered
on each side of the Easyplate. The resulting setup is completely oil proof and
provides long term reliability.
